at least one retina imaging system, each retina imaging system including;
a retina illumination source adapted to emit retina photons to a retina of the right eye or the left eye; and
a retina image sensor adapted to capture an image of the retina when the retina reflects the retina photons, the image of the retina having retinal biometric data; and
a controller adapted to control the at least one iris imaging system and the at least one retina imaging system, wherein the iris image sensor of the at least one iris imaging system captures the image of the iris according to operation of the corresponding iris illumination source, and the retina image sensor of the at least one iris imaging system captures the image of the retina according to operation of the corresponding retina illumination source.

Abstract
A multimodal biometric identification system captures and processes images of both the iris and the retina for biometric identification. Another multimodal ocular system captures and processes images of the iris and/or the from both eyes of a subject. Biometrics based on data provided by these systems are more accurate and robust than using biometrics that include data from only the iris or only the retina from a single eye. An exemplary embodiment emits photons to the iris and the retina of both eyes, an iris image sensor that captures an image of the iris when the iris reflects the emitted light, a retina image sensor that captures an image of the retina when the retina reflects the emitted light, and a controller that controls the iris and the retina illumination sources, where the captured image of the iris and the captured image of the retina contain biometric data.
